Works fine here. If you think there is a problem, please provide steps to reproduce the problem.

Note: triggering limit_conn limits with small static files with only one worker process isn't trivial as full request processing happens without going into event loop (unless sending to a client blocks), and thus there are no simultaneously processed requests to limit.

I download the files is very big, and has a speed limit. Is not a small file test.
I don't know if I caused problems with validation. And I in add access_log is abnormal, must be on the outside.
The location in my this is limit_conn and access_log is invalid, but limit_rate is effective.

The following is my configuration files

limit_conn_zone $binary_remote_addr zone=perip:10m;
server
{

listen 8000;
server_name s3.xxx.com;
index index.html index.htm index.php;
root /data0/storage/down/;



location ~ /premium {

secure_link $arg_st,$arg_e;


secure_link_md5 xxxxx$remote_addr$uri$arg_e;

if ($secure_link = "") {

return 403;

}


if ($secure_link = "0") {

return 403;

}


rewrite /premium/files1/(.*)$ /$1;
rewrite
/premium/files2/(.*)$ /user_upload/$1;


limit_conn perip 5;
limit_rate 3000k;

}

location ~ /free {

secure_link $arg_st,$arg_e;


secure_link_md5 xxxx$remote_addr$uri$arg_e;

if ($secure_link = "") {

return 403;

}


if ($secure_link = "0") {

return 403;

}


rewrite /free/files1/(.*)$ /$1;
rewrite
/free/files2/(.*)$ /user_upload/$1;
limit_conn perip 1;
limit_rate 30k;


}

location ~ /registed {

secure_link $arg_st,$arg_e;


secure_link_md5 xxxx$remote_addr$uri$arg_e;

if ($secure_link = "") {

return 403;

}


if ($secure_link = "0") {

return 403;

}


rewrite /registed/files1/(.*)$ /$1;
rewrite
/registed/files2/(.*)$ /user_upload/$1;


limit_conn perip 1;
limit_rate 50k;

}
add_header Content-Disposition 'attachment; filename="$arg_n"';
access_log /tmp/access.log;

}

Tested it is ok, but why can't different location separates the same zone name?

limit_conn_zone $binary_remote_addr zone=zsf:10m;
limit_conn_zone $binary_remote_addr zone=zsf1:10m;
server
{

listen 8001;
index index.html index.htm index.php;
root /tmp/test;

location ~ /zsf {

limit_conn zsf 1;
limit_rate 10k;

}

location ~ /zsf1 {

limit_conn zsf1 1;
limit_rate 10k;

}

}

The "location ~ /zsf1" in your config doesn't make sense as it's never matched, see http://nginx.org/r/location for details. Please use mailing list for further support question.
